Child Support Calculation Worksheet

IMPORTANT: THIS IS A PREPARATION GUIDE — NOT THE OFFICIAL COURT WORKSHEET

Colorado requires the use of official forms JDF 1820 (Worksheet A — Sole Physical Care) or JDF 1821 (Worksheet B — Shared Physical Care), with instructions in JDF 1822, for child support calculations.
This template provides the substantive content and calculation methodology to help you
prepare — but you must transfer your figures to the official worksheet before filing.
The official forms are available at https://www.courts.state.co.us/Forms/Forms_List.cfm?Form_Type_ID=93.
Do not file this document directly with the court.

11. State-Specific Notes

1. Income Shares Model: Colorado uses the Income Shares Model, estimating what intact households at different income levels typically spend on children, then allocating that cost proportionally.

2. HB25-1159 (Effective March 1, 2026): Major changes include elimination of the 93-overnight threshold, recognition of shared parenting time from the first overnight, removal of the 1.5x multiplier, and replacement of Worksheet A/B with a single unified worksheet.

3. Income Cap: The Schedule of Basic Child Support Obligations covers combined monthly adjusted gross incomes up to $30,000. Above that amount, the court has discretion but cannot order less than the top-of-schedule amount.

4. Age of Emancipation: Colorado extends child support to age 19 (or 21 if the child is in secondary school), which is older than many states.

5. Imputation of Income: Courts may impute income to a parent who is voluntarily unemployed or underemployed, based on the parent's work history, education, and earning capacity.

6. Child Support Commission: Colorado maintains a Child Support Commission that periodically reviews and updates the guidelines and schedule of obligations.
